“Moosin: God of Martial Arts” takes place May 21 at the DCU Center in Worcester, Mass. The main card airs on pay-per-view and costs $29.95.

After an extensive amateur career, Barnes opened his professional run with four-straight victories, including stoppage wins of regional-circuit stalwarts Sherman Pendergarst and Jeremy “Tiny” Norton. Barnes followed that success with a three-fight losing streak that included a TKO loss to heavyweight prospect Dave “Pee Wee” Herman at Bellator 5 in May 2009.

A primary training partner for Moosin headliner Tim Sylvia, Barnes bounced back with a TKO win over Iggy Zambrano in January. The bout with Wiuff will be Barnes’ highest-profile contest to date.

Meanwhile, Wiuff is among the sport’s most experienced active fighters. The 32-year-old has competed professionally since 2001 and has fought under the UFC, PRIDE, Sengoku, International Fight League, King of the Cage, Rumble on the Rock and Extreme Challenge banners, to name but a few.

Following back-to-back losses to Stanislav Nedkov and Muhammed “King Mo” Lawal in Japan, Wiuff has won six of his past seven contests. The lone loss came in a February TKO defeat to Mike Kyle.
